Guidance Software EnCase 6.2 and 6.5 does not properly handle a volume with more than 25 partitions, which might allow remote attackers to prevent examination of certain data, a related issue to CVE-2007-4035.

Guidance Software EnCase 5.0 allows user-assisted remote attackers to cause a denial of service (stack memory consumption) and possibly have other unspecified impact via a malformed file, related to "EnCase's file system parsing." NOTE: this information is based upon a vague pre-advisory. It might overlap CVE-2007-4036.

** DISPUTED ** Guidance Software EnCase allows user-assisted attackers to trigger a buffer over-read and application crash via a malformed NTFS filesystem containing a modified FILE record with a certain large offset. NOTE: the vendor disputes the significance of this issue, asserting that relevant attackers typically do not corrupt a filesystem, and indicating that the relevant read operation can be disabled.

** DISPUTED ** Guidance Software EnCase allows user-assisted remote attackers to cause a denial of service via (1) a corrupted Microsoft Exchange database, which triggers an application crash when many options are selected; (2) a corrupted NTFS filesystem, which causes the application to report "memory allocation errors;" or (3) deeply nested directories, which trigger an application crash during an Expand All action. NOTE: the vendor disputes the significance of these vectors because the user can select fewer options, there is no operational impact, or the user can do less expansion.

** DISPUTED ** Guidance Software EnCase does not properly handle (1) certain malformed MBR partition tables with many entries, which allows remote attackers to prevent logical collection of a disk image; (2) NTFS filesystems with directory loops, which allows remote attackers to prevent examination of certain directory contents; and (3) certain other malformed NTFS filesystems, which allows remote attackers to prevent examination of corrupted records. NOTE: the vendor disputes the significance of these issues, because physical collection can be used instead, because the vendor believes that relevant attackers typically do not corrupt an MBR or a filesystem, and because detection of a loop is valuable on its own.
